Abstract

A study has been made of the possibility of intramolecular cyclization of α-benzamido-β-(pentafluorophenyl)acrylic acid (IIa) with the object of synthesizing heterocyclic compounds. When the acid IIa was heated with potassium fluoride in dimethylformamide, 3-benzamido-6,7,8,9-tetrafluorocoumarin (III) was formed. Under the same conditions the methyl ester of (IIa) gave 2-phenyl-4-carbomethoxy-6,7,8,9-tetrafluorobenz[f]oxazepine-1,3 (Va). Some reactions of the latter have been studied.
